Example 2: Torque Arm Bracket with Fabricated Steel Torque ArmThe torque arm bracket can be ordered with the right angle reducer and the torque arm fabricated from thin steel by the customer to mount in an acceptable location.

Example 3: Fabricated Torque ArmUsing the mounting holes in the reducer housing, a torque arm can be fabricated to mount directly to the machinery. Notice that the fabrication must be 2 pieces with a slot in each piece to allow the connecting bolt to move in all directions.

Example 1: Torque Arm Bracket with Turnbuckle Torque ArmThis method uses a turnbuckle assembly that pivots from the torque arm bracket to mount to an acceptable location.

Torque Arm Mounting Methods (STOBER can supply the torque arm bracket. The user has to supply the torque arm for Example 1 and 2)

The following mounting methods are recommended for stabilizing the reducer without compromising reducer life.
